Using PIT telemetry for long-term monitoring of Austropotamobius pallipes complex populatins in a conservatin program

The contiuing decline of Austropotamobius pallipes complex populatins and the endangered status of the species have driven to plan and develop several conservatin programmes. Following key elements of management strategies, we conducted a long-term populatin monitoring in order (i) to evaluate PIT tag retentin and effcts of tagging on survival of crayfih and (ii) to map crayfih shelters and movements in long-term monitoring
